I guess it depends what you mean by "fuller"....if you mean the sound you hear on the street from a souped up car stereo system then I think the Merlin's will disappoint you....but this sound is not accurate music anyway it is mostly all resonant harmonic distortion.
I suspect that the Merlin VSM-M is doing a fasntastic job especially with your amplifier.
Proper base will not be boomy and room shaking all the time...most often it should be tight accurate and lean ...it is rare that the source material is "boomy", "fat" or "full" sounding.
Try adjusting your speaker placement...remember you get bass cancellations from rear walls at anything less than 2.8 meters from a rear wall!
Try either very far or very close to the rear wall...and avoid corners.
